Application iled may 3i,

T0 all whom 'it may concern Be it known that wefldnweno innnnsnn and HARRY lvl. Minn, citizens of the United States, residing atY Kenosha, in the county of Kenosha and State or' l/Visconsin, have invented certain new and useful improvements in' Boor-llinges, ci: which the following is a specification.

This invention relates to improvements in door hinves, and refers more specifically to an improved orm of hinge of the Sio-called concealed type, especially suitable for automobile doors, refrigerators, etc.

Among the salient objects or" the invention are to provide construction in which the labor and cost of mounting are very matej rially reduced without sacrifice or accuracy or reliability; to provide a construction in which the diiculty','high degree of skill and consequent eipense o so hanging two separate hingesthat their axes will exactly coincide and therefore operate perfectly, are avoided; this being accomplished by so oi'- ganizing the hinge that it is of duplex conu struction with the parts thereoll rigidly connected and alined; to provide a construction. which not only has the advantages above outlined but at the same time lends itself to manufacture by means of die and press work, thereby securing at the same time great accuracy and mimimum cost; to provide a construction which facilitates the proper mounting of the upholstery or ding on the inside ci an automobile body in the vicinity of thehinge, and which padding is ordinarily applied so as to conceal the hinge; and in general, to provide an improved construction of the character referred to.

The invention consists in the matters hereinafter described, and more particularly pointed out in the appended claims.

ln the accompanying drawingwhigure l is an inside face view showing our improved hinge applied to support an automobile door; parts of the hinge mechanism being indicated in dotted lines behind the upholstery and other parts in full lines, the upholstery being removed. Fig. 2 is a sectional view taken on the line 2-2 of Fig. l and looking in the direction of the arrows; Fig. 3 is a transverse sectional view taken on line 3`3 oi" Fig. l and looking downwardly.

nate the two main hinge members. The member l consists of a strap-like strip of plate metal provided near its end with approlrirnately rectangular Ubends 3, 3; these two beds having parallel sides and being alsoA accurately parallel with each other, as best seen in Fig; 2., Those portions of the blank which are bent to form the U-bends are wider than the remainder thereof and this excess width is arranged at that side of the hinge member toward the member 2; as shown clearly at the points designated 4c.

llhe member 2 comprises a main strap por tion 5 and two integral hinge arms 6 extending from one edge thereof and arranged accurately parallel with each other. rlhe member 3, like the member 2, is struck out of plate metal by means of suitable dies, and the hinge arms 6 are curved throughout the chief portions of their lengths, as best shown in Fig. 3; the terminal portions of said arms standing approximately at right angles to the plane of the body of the member 3. In order to very materially increase the rigidity and strength of these hinge arms without making them wide and unwieldy, the arms are formed of channel-shape in cross section, as seen clearly in Fig. 2, and they also widen out at their base ends where they merge into the main plate. The extreme end of each hinge is bent back upon itself to form a pintle eye 7 g it being noted that the marginal or channel side portions of the arms terminate immediately adjacent to the eyes aroper.

.lhe ll-bends of the member l constitute in edect hinge sockets to receive the arms 6 of the member 2, and these U-bent sockets are apertured to receive pintle pins 8 whereby the ends of the hinge arms are pivotally secured to the member i. is shown, the pint-le pins 8 .are simply straight pins inserted through the socket bends from side to side and slightly riveted at their outer ends to keep them in place. Each hinge member is provided with a suitable set of screw apertures whereby it may be secured to the door or the jamb, as the case may be.

ln applying a hinge of this construction, as for example to-an automobile body, the door j amb on the one hand and the door on the other are mortised out at some distance from their respective edges to receive the strap-like body portions of the respective members l and 2 of the hinge. ln the case sie lll@

parts in this respect is therefore important.

-in that it allows the strap to be set far enough away from the edge of the jamb so that a mortise or channelcan be formed to lreceive'it, the edge of which channel to a very large extent reinforces the securing screws in holding the hinge member absolutely against movement; and, secondly, the

construction provides for the securing of the ,N

upholstery as described. Moreover, ample width of socket is provided and the edge of the socket brought out flush with the j amb so as to act as a positive stop against the edge' of which the hinge armfmay contact when the door is opened to its limit without necessitatin an excessively wide strap as to the main ody portion of this member 1.

The hinge member 2 is very similarly mounted .in the innerface of the door; the strap-like body of said member being mortised into the face ofthe door at a suitable distance back from thev edge of the latter, and the mortise recess suitably shaped to receive the widened base portions of the hinge arms. provision is made for tacking the upholstery in place. as indicated at 9.

From the foregoing description it will be seen that the construction described carried into effect fully the stated objects of the invention. In this connection, the importance of forming the two hinge arms on a single securing plate of one member, and forming the two arm-receiving sockets as a part of the same strap or plate constituting the other member, is not to be underestimated. By this expedient only such skill is required of the hinge-setter as will enable'him to make mortises which will take the hinge members, and since they are alreadyassembled in fixed relation to each other, he can hardly go wrong in laying out the position of his mortises and need pay no attention whatever to the matter fof alinement of the two hinge members, because if they canv be secured in place at all they will of necessity be properly alined. The expedient of having the lower edges of the hinge-receiving sockets act as stops for the hinge-arms, of course, avoids the necessity of providing for such stops otherwise, and at the same time insures that the blows incident to arresting the swinging movement of the door will come upon the entire hinge structure itself In the'case of this member rather than upon a localized portion of the automobile body.

The structure lpossesses other advantages which need not be detailed.

IV e claim as oui' invention:

1. A door hinge comprising a generally flat facing member provided with a' plurality of relatively deep hinge-arm-receiving sockets oifset from the plane of the facing member and spaced remote from each other, each socket being open as to its facing side and as to one of its lateral sides, a second facing member provided with a plurality of hinge arms rigid with its main body and suitably spaced to register with the sockets 'of said first member, and suitable pintle connections whereby the ends of said arms are pivotally secured in said sockets to hinge about a common axis.

2. A door hinge comprising a sheetmetal strap-like member provided intermediate its ends with a plurality of spaced apart U- bends having parallel sides and constituting hinge-arm-receiving sockets, a second hinge member consisting of a strap-like plate proy vided with a plurality of integral arms eX- tending from one edge of the strap-body and curved to bring the ends of said arms into. alinement with an axis laterally offset fromv the plane of said strap body and remote fromA the proximate edge of the latter, and suitable pintle connections whereby the-ends of said arms are pivotally secured in the re` spective sockets with their pivotal aXes in alinement.

3. In combination with a vehicle-body and the door thereof, a door-hinge comprising one strap-like member provided with a plurality of hinge-arm-receiving sockets spaced apart from each other, another straplike member provided with a pluralityof arms integral with the main strap-body projecting therefrom and suitably spaced to register with the sockets of said first member, and suitable pintle connections whereby the ends of said arms are pivotally secured in said sockets with their axes alined, said strap members being secured to the adjacent inner sides of said door and body and spaced from said edges a suiiicient distance to permit the application of upholstery to said edges to conceal said strap members.

4. The combination of a door frame having mortises therein open at the edge and inner side thereofg a plate secured to the inner side of said frame and provided with sockets projecting into said mortises.I a door for said frame, and curved arms pivoted in the inner por-tions of said mortises at the outer portion of said frame, the other ends of said arms carrying a plate secured to the inner side of said door, substantially as described.

5. A duplex door-hinge construction adapted to provide in a single structure the equivalent hinge support and to perform th'e functions of two spaced-apart relatively distant and distinct alined hinges, said construction comprising a strap-hke facing 10 within the respective sockets in axial alinement with each other, and arms secured to' v said door spaced to register with the sockets l said. rst member, curved to enter the respective sockets, and connected with sald EDWARD ANDERSEN.
